Building a web application begins by outlining user roles, essential use cases, and the data schema. A strong MVP concentrates on main workflows, intuitive navigation, and consistent UI elements, enabling rapid delivery without becoming a brittle collection of scattered screens.

Post-launch, scalability and reliability take priority: performance budgets, caching, robust authentication, and well-defined API contracts. With effective monitoring, CI/CD, and deliberate architecture, teams can iterate more quickly while preserving codebase stability as features and traffic expand.
